ONLYOFFICE

The suite provides web‑based editors for text documents, spreadsheets, presentations, forms, PDFs and diagrams, supporting Office Open XML formats and enabling real‑time collaborative editing. It includes additional tools such as AI‑assisted features, spell‑checking, accessibility options, dark mode and security services. The editors can be integrated with the broader ONLYOFFICE Workspace platform, which adds project management, CRM, shared calendars, mail and file‑sharing capabilities.

It is self‑hostable and distributed under the AGPL‑3.0 license, offering a free tier without subscription requirements. The software can be deployed on Windows, Linux or via Docker, and is designed for organizations that need an on‑premises, open‑source alternative for document creation and collaboration.

Developers can extend functionality through a plugin API and marketplace, while the platform supports localization in dozens of languages, right‑to‑left scripts and specialized character sets. The solution is positioned for teams and enterprises that want to manage documents, projects and customer relations within a single, self‑controlled environment.
